“Our 3D Printer filament is a place where your imagination is brought to life. Designed with superior quality and best user experience in mind, Our 3D Printer Filament is manufactured with industry-leading high precision tolerance (0.02MM) to ensure that you spend less time trouble shooting and more time creating! Filament Storage Tips？ 1. Since PLA material is made from biodegradable sources, it is susceptible to moisture. We recommended storing filament in a sealed plastic bag or box after each print (a large ziplock or Tupperware works well). 2. In extreme cases where the filament gets damp, you can bake it in an oven with 50-degree Celsius for about an hour to restore its dryness. Reminder: Each time after use of your 3D Printer Filament？ Be sure to insert the free end of the filament into the hole to avoid the filament being tangled for next time use.”
